.mnovmnr m ANTIJ'RICTION w msenacnumwmmmmmmzmamung mofmm To all whom it mwy concern Be it known that we, U. H. Benn, JEREMYLAKE,

and Loreen szsson of North Easton, in the county of Bristol, and State of Massachusetts, have invented a new and useful Improvement in Anti-Friction Washers; and wedo hereby declare that the following is-a 1 full, clean-and exact description thereof, which will enable othersskilled inthe art; to make and use -the same, reference being had to the accompanying drawings, forming part of this Specification. 7 This invention relates to improvements in washers for vise-screws, and for other similar purposes, the objeot'of which is to make them as fi'ictionless as possible. a 1

It consists of a washer, composed of two rings and a tubular section, one of the said rings and .the tubular section formed to have an annular recess when vjoined together, which is filledv with spherical balls,

which take the pressure of the screw or not fronirhe other ring, which is held in contact with the balls by one outer annular-projection taking behind an 'inner annular, projection of the tubular section, and which is free to turn on the balls by the action of the nut when being screwed up, aswill be niore-ihlly described on reference to the accompanying drawings, wherein Figure 1 represents a horizontal section on the line zzQifigQ and, l

Figure 2 represents a transverse section on the line 9 y of fig. 1.

Similar letters of reference indicate like parts.

A and B represent two rings, having central perforations for the belt or shank of the screw to pass through, and are of about the same diameter.

The ring A hasan annular recess, C, in one face, and a section of a tube. 1), secured to its periphery by end with an inwardly-projectingannulsr ledge, F.

The ring B is provided, at its inner end, witha corresponding annular outwardly-projecting ledge, which takes behind the ledge F, and is-the means, together with the latter, of holding 'theh'ing'B in its position, while allowing it to turn'wiih referenceto the ring A. The annular recess 0 is provided with spherical balls, H, of a diameter slightly greater than the depth of the said recess, between which are alternate balls, I, ofless diameter. I Y When the washer, thus constructed, is, under th action of a nut, being screwed down on a bolt or on a wise-screw, between the bearing and the shoulder of the screw, the pressure will be taken byjzhe balls H between the two parts, and one allowed to turn with the nut'or screw on the said balls, thereby very greatly reducingithe friction, as will be readily understood.

The oifice of the smaller balls is to keep the larger ones in place, and prevent their sides oomingin contact. Having thus described our invention, We claim as Patentl The combination of the parts A, B, and D, and the spherical balls, substantially asand forv the purpose described.
